To all whom it may concern:

Be it known that I, DAVID C. SASSEMAN, a citizen of the United States,residing at 1 River Forest, in the county of Cook and 3 State ofIllinois, have invented new and useful Improvements in Machines forApplyv ing Metal Ornaments to Leather, of which the following is aspecification, referencebeing had to the accompanying drawings, 1forming a part thereof.

The purpose of this invention is to provide a device designed especiallyfor attac 1 ing what are called spots to harness leathers and the like,but not limited to that particular use.

It consists of the features of construction 1 shown and described asindicated in the I 1 claims.

In the drawings:-Figure 1 is a side elevation of a spot machine,so-called, embody- 1 ing this invention, shown in position ready 3 foroperation. Fig. 2 is a fore-and-aft section of such machine axial withrespect to l the spot-holder, showing the parts in the position occupiedat the commencement of the l spot-applying stroke. Fig. 3 is a viewsimil lar to Fig. 2, showing the parts in position at the completion ofthe riveting or spot-securing action. Fig. 4c is an enlarged detail 1view of the spot-holding device and its operating connections. Fig. 5 isa section at i the line 55 on Fig. 1. Fig. 6 is a similar View showingthe gage reversed. Fig. 7 is an axial section of a modified form of spotholder.

The machine, as a whole, in which this invention is embodied, is of thenature of a press which may be arranged, as illustrated, i to beoperated by the foot of the operator, and which comprises a base, A, andan overhanging head, B, the base being adapted to hold a riveting diskor anvil, so-called, 1, 1

plunger, 2, reciprocates. The reciprocation of the plunger may beefiected by any mechanical devices familiar for such purpose in diepresses, riveting machines and the like. For the purpose of the desiredaction in securing metal ornaments called spots, this plunger has apositively actuated central member, 3, and sleeved upon it a y1eldingmember, 4, below the lower bearing of the member, 3, stopped betweensaid bear- 1 ing and a stop at the end of said member, 3,

which is most conveniently afforded by the the plunger member, 4%,

spot driver, 6, which has astem, 6, by which it is screwed into the endof the reciprocating member, 3, this spot driver being a disk which isof greater diameter than the said member, 3, and so stops the yieldingmember, a, as indicated. The lower face of the spot driver, 6, isconcaved to suit the face of the spot represented at O. A spring, 9, iscoiled about the reciprocating member, 3,

above the lower bearing, B said spring being stopped at the upper endagainst the guide block or head, 3 of the plunger member, 3, whereby thespring operates to yieldingly retract the plunger until the lowerstop,-the spot driver, 6,-forces the yielding member, l, up against thelower side of the bearing, B

10 is a cam which operates on the top of the block, 3, for driving theplunger downward when the cam is rocked by the foot of the operator on apedal, not shown, connected with the chain, 11, which is attached at itsupper end to the arm, 10, of the cam. The yielding member, at, has anoffset arm, 12, provided with a depending which there is hinged a spotholder, 1a. This spot holder is an apertured disk or ring of which theaperture fits the spot, and has grooves, 14L, at opposite sides toengage the tangs or clenching fingers, C of the spot, O. This spotholder has an offset lug, 14, by which it is hinged to the dependinglinger, 13, of the yielding member, l, of the plunger. The purpose ofthe spot holder is to hold the spot in position to have its tangs, Odriven through the leather into encounter with the clenching die oranvil, 1, for clenching on the lower side of the leather; and for thispurpose, it occupies a position transverse to the stroke of the plungerwhen the operation is to be performed, but this is not a convenientposition at which to introduce the spot. The most convenient position ofthe spot holder for introducing the spot is inclined at an angle ofabout forty-five degrees, as seen in Fig. 1. In order to adapt the spotholder to assume and retain this position for the purpose and during thetime of introducing the spot, not only is it hinged, as described, tothe depending finger, 13, of

but there is also provided a pressure finger, 16, hinged to the offsetarm of the plunger member, l, extending down along and preferably in aslot in the back edge of the finger, 13, past the hinge of finger, 13,to

the spot holder to said finger, a spring, 17, being provided acting uponthe pressure finger for pressing it inwardly at the lower end againstthe hinge lug of the spot holder. This hinge lug has the end squared, sothat the pressure of the pressure finger against it causes said spotholder to project horizon tally ;that is, across the direction of strokeof the plunger;but if swung around to vertical position, the pressurefinger simi larly operates upon the longitudinal edge of the lug, 1 t tohold the device vertical. At a half-way intermediate position, thepressure of the finger will tend to maintain the spot holder at45-degree-incline position; but for greater certainty of position, thecorner between the end and side of the lug, 14 is preferably beveled offat an angle of 45 degrees to receive the pressure of the pressurefinger, thus definitely positioning the spot holder properly for easyintroduction of the spot. In this position, the forward edge of theinclined spot holder stands approximately in line with the axis of theplunger overhanging the leather, D, to which the spot is to be afiixed;and upon the descent of the plunger, the spot holder encountering at itslower edge the surface of the leather is forced upward at that edge,swinging it about its hinged pivot as the plunger descends. A movementof about twenty-five degrees about that pivot carries the squared end ofthe lug, 14 to a position at such an angle to the face of the pressurefinger that the pressure of the latter operates to force the spot holderto complete the movement to horizontal position with a snap, lifting itslower edge off the leather, so that the further descent of the plungerbrings it down broadside on to the latter. The descent of the spotholder being arrested by this broadside encounter with the leather, theentire yielding member, 4:, is arrested, while the member, 3, continuesto descend, and the spot driver, 6, at the end of said member forces thespot out of the spot holder, driving its tangs through the leather andon to the clenching die or anvil by which they are reversed into theleather, securing the spot as desired. Upon the release of the operating cam, 10, the spring, 9, reacting lifts first the plunger member, 3,until the lower stop,the spot driver, 6,encounters the yielding member,4, picking it up and carrying it on up until stopped by the lower sideof the bearing, B The operator can now swing the spot holder again intooblique position and repeat the operation.

For gaging the distance of the spot from the edge of the leather, anyconvenient form of gage may be mounted upon the press bed. In order toobtain the widest range of adjustment within the capacity of the pressstandard, the gage employed is a T-shaped element, E, having the gagelip, E extending along the cross arm of the T at one side, the stem ofthe T having at the opposite side a groove, E which engages a rib orfeather, A on the base, A, of the press, a set screw, 20, being providedfor securing the gage at any point which may be ad usted along'thefeather. For steadiness of the gage, it is desirable to have as long abearing as possible for engagement of the T stem with the rib orfeather, but obviously, the length of the stem added to the range ofmovement cannot exceed the distance between the back arm of the pressstandard and the rear edge of the spot holder, But in order to have thebenefit of as long bearing as possible, and at the same time to utilizethe entire distance from the position of-the spot holder and clenchingdie back to the standard for adjustment of the gage, and be able tosecure the spots as far from the edge of the leather as that entiredistance, the T gage is made reversible, the rib, E having both facesmade true and the said cross arm being cut away at E* at the outerside,that is, opposite the end of the T of the stem,-to accommodate thestandard when the gage is mounted with the stem projecting forward forengaging the rib or feather. From the rearmost position at which thestandard of the press enters the recess, E of the gage, the gage may bemoved forward half way to the rear edge of the spot holder, and forfurther forward adjustment it may be reversed so that the stem projectsrearward, and when thus reversed and set with the end of the stem backagainst the press standard, the forward edge of the gage rib occupiesthe identical position occupied by the opposite edge of that rib beforeit was reversed, and from this position the gage may be adjusted forwardto the rear edge of the spot holder.

For locking the latch, 16, at the position shown at Fig. 4 fordisengaging the spot holder and substituting a different one, a detenthook, 18, is pivoted upon the top of the ofifset arm, 12, of the plungermember, 2, the hook nose, 18*, being positioned for engaging the outsideor upper arm of the latch when it is swung to the position sh own.

In Fig. 7, there is shown a modification of the spot holder connection,which consists in a springpressed plunger, 16, in lieu of the latch, 16,the spring, 17, operating to thrust the head of the plunger down uponthe upper edge of the lug, 149, of the spot holder for holding ityieldingly in either of the three positions,horizontal, inclined orvertical.
